9. United Arab Emirates
Population: 5.47 million
Percentage of millionaire households: 4.0%
Of the Gulf state's seven members, no emirate was hit harder by global financial turmoil than Dubai, the financial and transport hub of the Middle East. It was on the brink of default in 2009 because of its heavy exposure to the imploding real estate market. Central bank intervention helped Dubai survive. The country counted 60,000 millionaire households last year, according to The Boston Consulting Group's recent report. Among the richest inhabitants are members of the al Ghurair family, who, through their namesake group, hold stakes in banking, malls and manufacturing.
